I know that we have talked about pricing. I have seen it reported that Moderna and Pfizer are sitting on close to $23 billion in profit globally and have actually assured their shareholders that they're going to raise the prices in the coming months. This is going to make a bad problem worse.

I'm wondering what your strategy is for price fluctuation, and whether our contracts locked in at the originally negotiated price.
